Additionally, the tyre pressure table may also state tyre pressures for different load conditions. These are defined in the tyre pressure information table as different numbers of passengers and amounts of luggage. The actual number of seats may differ – for more information, please refer to the vehicle's registration documents.
The tyre pressure values given for partly laden vehicles are minimum values which offer you good ride comfort.
You can also use the tyre pressure values for a fully laden vehicle. These are always allowed and permissible. However, in a partially laden vehicle, the ride is not as comfortable and energy consumption is only minimally reduced. In addition, wear is greater in the middle of the tyre tread.
Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure.
On vehicles fitted with the electronic tyre pressure monitor, the tyre pressure can be checked using the on-board computer.
Set the correct tyre pressure before loading the vehicle. Once the vehicle is laden, check the tyre pressures and correct them if necessary.
The vehicle has been parked with the tyres out of direct sunlight for at least three hours.
The vehicle has travelled less than 1.6 km.
A rise in the tyre temperature of 10°C increases the tyre pressure by approx. 10 kPa (0.1 bar/1.5 psi). Take this into account when checking the tyre pressure of warm tyres.
